According to foreign media reports on May 5th, Tesla announced a high-profile lithium battery energy storage system, in which the "Powerpack" for enterprise users, the price of 100 kWh is 25,000 US dollars, has reduced the average energy storage cost to a considerable Amazingly $250 per kWh, it is generally believed that if the average energy storage cost drops to $100 per kWh, it will ignite the energy storage revolution. The power of the Tesla GigaFactory is approaching this goal at full speed, but there is a small new Create a business and think that it can be done now.
The startup, FreeWire, raised $425,000 in initial funding, and with the US Navy funding $500,000, how can it surpass Tesla's big family? In fact, the principle is not difficult, that is, the use of second-hand batteries.
FreeWire and Nissan cooperate with NEC's joint venture Automotive Energy Supply Corporation (AESC), which is second only to Panasonic, the world's second largest supplier of lithium battery batteries for vehicles, with a market share of 21%, 2014 The best-selling electric car in the year is Nissan Leaf, whose battery is supplied by AESC. Nissan tests the battery every month and replaces the lithium battery with declining performance every six months. For Nissan, for Nissan Inventorying these second-line batteries is a hassle, but the performance of these batteries may not be enough for electric vehicles, but it is still useful for energy storage.
As a result, FreeWire acquired these used batteries at a price of one-sixth of the new battery. The first step was to use electric vehicles for electric vehicles. These used batteries were assembled into a mobile charging vehicle with a total capacity of 48 kWh. For the electric car to be charged in the parking lot, airport, enterprise factory area where there is no charging stand, the mobile charging car can be pushed to any parking space in the parking lot to help the electric car to charge, so that the parking lot can save a lot of charging. The cost of the seat can provide a small number of electric vehicle owners charging services, and these used batteries can have a life of 5 years in the case of two charge and discharge cycles per day.
Because of the use of used batteries, FreeWire devices cost only $100 per kWh. CEO Arcady Sosinov said that the battery industry will not be able to meet the cost targets until 2030, they use low-cost batteries to reduce costs. So I have done it now.
Arkadi Sosinoff’s ambition is not just to charge mobile electric vehicles. He believes that the business opportunities of second-hand batteries are quite large. The same system can also be used to replace diesel generators, to supply electricity without electricity supply, or as a backup. Power is supplied, and lithium battery power has a greater advantage than diesel generators, that is, no noise or exhaust gas is generated. If you want to do a movie theater mosquitoes outdoors, use a lithium battery system is clearly better, while many developing China's home phone base stations have backup power grid instability due to demand, in the past these systems to replace diesel generators business by the bizarre alone Laxon is monopolized, and now it can compete with the low cost of used batteries.
Furthermore, the second-hand battery system can also enter the home and enterprise energy storage field that Tesla is entering with great fanfare. However, the development of second-hand batteries will not only be played against Tesla because Tesla develops electric vehicles. The same will face the replacement of a large number of second-hand batteries, these second-hand batteries can be reused to make energy storage equipment, which is also a big benefit for Tesla.
FreeWire's idea of ​​using used batteries has also inspired the energy storage industry. In the past, the decline in lithium battery performance was a major problem in the industry, but instead of thinking about the use of batteries, it could create many price-elastic opportunities.
Titanium alloy is a class of metallic materials widely used in various high-performance applications. It is a combination of titanium with other elements, such as aluminum, nickel, molybdenum, and vanadium, to enhance the properties of pure titanium.
One of the key advantages of titanium alloys is their high strength-to-weight ratio. They are significantly lighter than steel while being just as strong, making them ideal for aircraft, missiles, and spacecraft. Moreover, titanium alloys possess excellent corrosion resistance, which makes them highly suitable for marine, offshore, and chemical processing environments.
In addition, titanium alloys exhibit good biocompatibility, which makes them suitable for medical implants such as artificial joints, dental implants, and pacemaker cases. They also have high fatigue resistance, low thermal expansion coefficient, and excellent weldability.
Overall, titanium alloys have become an essential material in many industries, including aerospace, marine and offshore engineering, chemical processing, biomedical engineering, and sports equipment. As research continues to advance, it is expected that more innovations in the field of titanium alloys will arise, paving the way for even safer and more efficient applications.
